pH?

heres some quality questions for you folks

1)what lowers pH?

A) carbon dioxide
B) lack of gas exchange
C) nitrification
D) metabolic waste
E) all of the above


2) what raises pH?

A) bicarbonate
B) calcium
C) carbonate
D) borate
E) hydroxide
F) all of the above

 

1)e//////////
2)f//////////
highlight to see

am i right?

 

1)CO2, lack of gas exchange causing excess CO2, nitric acid, metabolic waste
2)hydroxide, carbonate, calcium, borate

lmao, stick to the program. thats not one of the picks. lol.

 

So you are trying to be tricky reef guru? You left out some other parts of the equation...

1. E
2.E, and C to an extent, the buffers have little increase in pH as compared to increase in alkalinity so you can look at it both ways, that they DO raise pH and that they DON'T.

Good luck all

 

Hey Guru! According to my knowledge/experience:

Q1:
E) all of the above
Most of the oxidation reactions (catabolic) lead to formation of ions commonly found in acids (nitrite acid, phosphatic acid, carbonate acid). However, proper buffering in our small reef systems "wipes" out free protons from these acids, and therefore we are only left with ions that can re-enter anabolic biochemical pathways, and be utilized by bacteria/algae/some corals.

Q2:
E) hydroxide
You have listed bicarbonate, calcium, etc... Only hydroxide anions effectively rise pH. However, proper hydrocarbonate/carbonate balance is required for proper buffering capacity of water. Therefore, both are required to maintain healthy pH/buffer conditions in marine environment.

 

I would have to say.....

1. E
2. F
